Casio G-5600E Tough Solar - World Time, Alarm, Stop Watch, Timer, Oct. 2011
I have turned "ON" all the functions
for this picture. PS stands for a Power Save function which puts this Casio "asleep" if the watch is in a darker area. A function making a lot of sense for regions with less sunshine. SNZ stands for SNOOZE, ALM for ALARM (there are 4 alarms and the hourly time signal SIG). L - M - H stands for the battery charge level: Low - Medium - High. The manual says that if the watch is full charged, it should have a power reserve of 11 months (under certain conditions, little alarm and light use). And last but not least, A.EL stands for Auto-Light function. A convenient way to illuminate the display by tilting the wrist.
